More explicitly, achamber 29 for air under pressure of the head pressure is existent inthe upper portion of the vessel H, above the liquid, or water, M in saidvessel, and an air conveying connection 30 leads from said chamber 29into an upper portion of the chamber 28. An inlet 3| of the airconveying connection 3!! is controlled'by a needle Valve 32 itselfcontrolled by a float 33 within the chamber 29. The construction andarrangement are such that the needle valve 32 is normally in the opencondition of the iinlet 3|, and that said needle valve will cause saidinlet to become sealed closed in response to elevation of the liquid, orwater, level in the vessel ll". Air under pressure is adapted to passfreely from the chamber 29 through the inlet 31 amiethe .-ai ..conveyingconnection 30 into the chamber 28, but liquid, or Water, is precludedfrompass-ing the inlet 3| due to the fact that with rising. of liquid,or water, in the vessel H to .the elevation-cf the float-33 .said floatwill be actuated to.cause.the. needle valve.32 to seal. said inletf.3'lclosed. .A.manually actuable valve 34 in the. air connecting pipe-30 isfor controlling the passageotair underpressure from the chamber29..in'to.lthe chamber 28'. A branch pipe 35 leads intothe connection 30and may be employed for thepurpose of maintaining or increasing the aircushionin said chamber '28, as by means of an airpump (not shown), orotherwise. A manually actuable valve in the branch pipe 35isrepresentedfbyreference character 36.

.It, .will'fbe observed. that. the reservoir I6 is ,isolate'd ifrom. thevessel II in such manner that there is no possibility for interchange ofthe liquid, or watenfl'llgand"theiliquicl, or chlorine solution, I!between said vessel .and reservoir. That is, no liquid can possibly flowfrom the vesselll l'lto' the reservoir L6, or from said reservoir tosaid "vessel.

A stem forthe valve 5|]passes freely upwardly through the opening 49,. and the upper end ofsaid stern 5| is rigid with afloat 52 within thecontainer 4|. Theconstruction and arrangement are such that a constant level of theliquid or chlorine solution is maintained in the container 4|. 1 Statedotherwise, the level of the liquid, or chlorine solution, ll, of courseflowing to the container 4| from the reservoir l6, in said container 4|is maintained substantially constant by the float 52. A tilt .bucket 53is situated within the mixture receiving location or compartment 42 ofthe mix ing receptacle 3'!, at elevation above the base 54 of thehousing 38. Said tilt bucket 53 is pivotally supported, as at 55, upon aside wall of said housing 38, in adjacent relation to the partition 40,for swinging movement in a vertical plane toward and away from saidpartition. The pivotal support or axis 55 for the tilt bucket is spacedfrom the longitudinal axis of said tilt bucket, at the left of saidlongitudinal axis; that is, at the side of the axis of the tilt bucketadjacent the partition 40; inthe disclosure as made. i A counterweight.55 upon the side wall of the tilt bucket and adjacent the partition4!), and a counterweight 51 upon the base of said tilt bucket. are forthe purpose of retaining the tilt bucket when empty or substantiallyempty in upright position, as disclosed in full lines in Fig. 2 of thedrawings. The construction and arrangement are such that upon areception of a predetermined amount of liquid, or water, l4 the tiltbucket 53 will become'tipped, or moved to the dotted line position insaid Fig. 2, thus to cause liquid, or water, to become removed orspilled from said tilt bucket and deposited into the mixture receivinglocation or compartment 42. After tipping, thetilt bucket will move fromits dotted line position to its full line position in Fig. 2, due to theweight of the counterweights' 56 and 51. A stop 58 is for limitingswinging I movement of the tilt bucket53 in direction to ward thepartition 40, and a stop 59 is for limiting swinging movement of saidtilt bucket di rection away from said partition and toward the base 54of the housing 38. 1 v

An arm 60, rigidly secured to an upper portion of the tilt bucket 53,extends outwardly and downwardly from said tilt bucket at the sidethereof adjacent the container 4|, anda dipper 6| fixed to the outer endof saidarm 6G is adapted to be submerged in liquid, or chlorinesolution, in said container 4| when said tilt bucket is in uprightposition. With each tipping of the tilt bucket 53, ormovement of saidtilt bucket from the full line position in Fig. 2 to the dotted lineposition, a

dipper fullol liquid. or chlorine solution, is removed from thecontainer 4| and deposited in the mixture receiving location orcompartment 42.

That is, upon the tipping of the tilt bucket. the dipper is moved fromits .full line position to its dotted line position in said F'ig. 2.Upon return of said tilt bucket to uprightposition. said dipper becomesagain situated below the level of the liquid, or chlorine solution, insaidcontainer 4|.

Assuming valves l5,f64 and-69to 1381013811, and airaunder- -pressure tobe present in thesystem, itwillbe-evident'that with flow of liquid, or

water, from'the supply pipe Ill past the connecting'pipe l2,the.gatevalve 8| and the discharge pipe 65, there will be flow of liquid, orwatc -from the. vessel [I through the'feed-pipe 62 intothe tilt, bucket'53, as well as capacity for fiow'from the mixture receiving location orcompartment 420i the :mixing receptacle 31 through the dischargepipe' 65to the downstream side of said supplypipe i=0, when the gate valve 8| isset'to cause-the: pressure within said mixing receptacle 31 to havevalue less than the pressure within the upstream side of the supply pipe"Landrhence less than the pressure within the vessel I. It, will alsobe; evident that-with increase of the differentialin pressure betweenthe upstream and downstream sides of the gate valve 8|, there willbe-proportional increase in the flow of liquid, or water, M from thevessel ll into the tilt bucket 53;:and-vice versa. Naturally, there willbe increase-of difierential in pressure with increase in therateof flowof liquid, or water, from the supply pipe lfl'out of its outletconnection, and vice versa, and the rate of increase or decrease ofdiflerentialin pressure will'vary in proportion as there is increase ordecrease in the rate of flow of liquid, or water, from'said supply pipepast the gate valve 8|. Thatis, the 'amount of liquid, or water, causedto enter the tilt bucket 53 from the vessel II will be directlyproportional to the amount of liquid, 'or water; which is caused to flowfrom thesupply'pipe l0 past the gate valve BI and the discharge pipe 65,no matter what may be the rateof speed of travel of the liquid, orWater, throughz'said supply pipe.

As will be apparent, substantially all of the liquid, or 'water, whichreaches the mixing receptacle 31 by way of the feed pipe 62 first entersthe tilt bucket 53; and is spilled from said tilt bucket to themixturereceiving location or compartment 42'. Each'time the tilt bucket unloadsits content to-said mixture receiving location or compartment 42 thereis also a dipper full of liquid, or chlorine'solution, dumped into themixture receiving location or compartment. Stated differently, therelative amounts of 'liquid, or, water, H- 'and liquid, or chlorinesolution, l1 fed to the mixture receiving location or compartment 42 areaccurately measured. The relative proportions of the different'liquidsto be mixed will obviously depend-upon the relative sizes of the tiltbucket :53'and the dipper'BI, etc. The rapidity of action'of-the tiltbucket can be controlled by the adjustment of the'pressu're differentialcreatmg-means, such as the valve 8I,-'or by regulation of the capacityfor'flow'through'the feed pipeGZ, as :by manipulation of the valve 64,or by both adjustment'of said pressure differential creating means andregulation of flow through said feed pipe 62. A 'range'ofsizes ofdippers, such as 6|,

. ca be'employed. Obviously, the feeder apparatus includes provision'for a very flexible feed as'to volume of liquid, or chlorine solution,l1 in proportion to liquid, or water, l4.

The liquid, or chlorine solution, ll fed to the mixture receivinglocation or compartment 42 becomesathere intermingledwith, and onlywith,.the liquid, or water, I4 which flows .from the vessel through thefeed pipe 62 into themixingreceptac1e3'l. -Evidently, upon union of vtheliquid, or chlorine' solution, which reaches the mixing redicatorcontinues.

ceptacle' from the reservoir It, with the liquid, or water, I4, whichreaches the mixing receptacle from the vessel l I, said liquids, waterand chlorine solution, will be mixed together in preciselytheproportionswhich were predetermined, regardless of the value of thedifferential in pressure between in the chamber 28'exerted upon thesurface of the liquid, or chlorine solution, within the indicator by wayof th air connections 26 and 21, past the valve 19 while open.

, Bhe feeder apparatus, it will be observed, is of quite simpleconstruction and includes no delicate' parts or minute passages liableto become clogged. The only movable parts Of the feeder vessel H to themixing receptacle 31 rejoins, and v the liquid, or chlorine solution,fed to said mixing receptacle from the reservoir IS joins, the

main body of liquid, or water, onpassage from,

the supplypipe ID to its outletlconnectiona The mixture of liquids, suchas water and chlorine solution, which flows from the mixture receivinglocation or compartment 42 of the mixing receptacle 3'! through theconcavity .61 and the discharge pipe 65 to the supply pipe I0, may

carry along with it some air, thus to cause pressure of air in saidmixing receptacle to become reduced. Should this occur, liquid levelmight possibly be caused to rise in said concavity 61. With rising ofliquid level in the concavity 61 the float 75 will be elevated thus toremove the needle valve -l4 from its seat and permit air under pressureto flow from the chamber 28 through the air co-nnection26 and the airpipe 70 into the mixing receptacle 31. Upon replenishment of air underpressure in said mixing receptacle the level of liquid in the concavity,61 will be caused to fall, by reason of pressure of the air,

to extent permitting the float to become de-i pressed to cause theneedle valve 14 to engage its seat and cut off further how of air intothe mixing receptacle; Evidently, the construction and arrangement aresuch as to preclude the possibility of back flow of mixed liquids fromthe discharge pipe 65 to extent liable to cause overflow of thepartition 40 or interference with operation of the tilt bucket 53 andthe dipper 6|. When the needle valve 14 is opened, by elevation of thefloat 15, there is flow of air under pressure from the chamber 28 intothe mixing receptacle 31' which will preclude rising of the liquid levelin theconcavity 61 even to extent sufficient to cause said float 15 toremain in elevated condition, much less to extent to flood over.

the partition 40 or to reach the lowermost operating position of thetilt bucket.

One way to accurately measure the amount of liquid, or chlorinesolution, ll being fed from time to time from the reservoir I6 into thecontainer 4|, the capacity of the dipper 6| being known, is to count thenumber of tips per unit of time of the tilt bucket 53. Another and moreconvenient "way to accurately measure the amount of liquid, or chlorinesolution, I! being consumed in the feeder apparatus from time to timeislto close the valve 89, thus to shut off flow from the reservoir Hi tothe well 44 and permit flow from the liquid level indicator 22 to saidwell, and take readings from the calibrations 23 upon said liquid levelindicator as flow from theliquid level in- Flow of liquid, or chlorinesolution, ll from said indicator 22 into the well 44 is caused when thevalve 80 is in closed position by reason of pressure of air underpressureapparatus during its operation in practice are the tilt bucket53 with the dipper 6| and the several floats and their appurtenances.
